' WALL-TIE.

To all whom it may concern:

- Be it known' that I, HENRY H. LAMPERT, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain newand useful Improvements in lVall-Ties, of whichthe following-is aspecification. The main objects of this invention are to provlde animproved device, designated as a-wall tie, for use in concrete or other building constructions in such a manner that.

various elements or devices intended to form a part of .thecompleted structure, may be secured to a wall, ceiling, or other'part of the structure; to provide a strip of metal having an improved arrangement of anchor parts thereon which are adapted to be embedded into the wall so as to-locate the strip on the face thereof; to provide an improved formation of means insaid strip which enable a practical elongation of the portions between two anchor parts in order to permit same.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figure l is a perspective view of a section of a Wall tie constructed in accordance with this invention.

Fig. 2 is a perspective view of a section of a concrete mold showing the manner in which the'tie members are applied to the form and their ultimate arrangement in the concrete.

Fig. 3 is a perspective view of amodified i a section of a wall tie constructed in accordbuilding construction may be attached to such wall or the like.

In the specific embodiment herein shown,

7 the strip 1 is of wrought metal and is doubled'iipon itself at intervals so as to form transversely disposed anchor parts 2 the Specification of Letters Patent.- Patented J 25 1921 Application filed January 23, 1920. Serial No. 353,413.

'to form the wings 3 extending in opposite directions. A

Corrugat1ons4 are formed in the strip 1 crosswise thereof between adjacent anchor parts, 2 so that after the tie member has been embedded in a wall, the .portions between adjacent anchor parts 2 may be practically elongated when said portions are bowed outwardly away from the face of the wall, as will more fully hereinafter appear. These corrugations are preferably located adjacent to the bends 5 which occur in doubling the strip upon itself to form the anchor parts 2. I

This improved wall tie is formed by first running the strip 1 through a suitable machine or pair of dies, cutting longitudinally -disposed slits therein at predetermined intervals along its length, after which the strip is run through another set of dies or another machine so that the strip is doubled upon itself at the points where said slits are formed in such a way that the slits extend inwardly from the ends of the double-over portions so that said eiids may be then bent over to form the oppositely disposed wings 3 extending .in the same general direction as the strip 1. The corrugations 4L may be formed either at the time the slits are cut or at the time the strip is doubled=upon itself as may be found most expedient.

The tie member is particularly designed I for use in connection with concrete building constructions. "However, it is also suitable foruse with other forms of building involving the use of plastic material in which the anchor parts 2 may be embedded so as to leave the strip exposed along the face of the wall. The most general use to which this wall .tie is put is that of bonding brick or stone veneer to concrete. Y

The device is used by securing theface thereof against the sides 6 of the mold by driving nails or'other suitable fastening means through apertures 7 formed in the strip. 1 One of the time members is shown in place in Fig. 2. Afterthe concrete has been poured into a mold inwhich several 'ofthe wall-ties have been suitably arranged, the anchor parts 2 and wings 3 become embedded in the concrete with the face of the strip substantially flush with the face of the concrete.

After the mold sections have been removed, the ends of the fastening means by out so that there is a practical elongation of the section of the strip 1- between the anchor parts 2. In Fig. 4, an S-shaped member 8 is shown secured in place in the aforesaid manner. If such a bonding memher is used for bonding brick veneer to the face of the concrete, these bonding elements 8 are arranged so as to be placed in the mortar between the bricks.

Ifthe wall tie is used for other purposes than bonding brick veneer, the form and manner of attachment of the elements to the strips may be varied in any way that may be found most desirable.

As will be obvious, other modifications than those herein shown may be made, and those which are herein shown may be furthermodified or altered, or have details thereof omitted without departing from the spirit of this invention as defined by the following claims. I'claim:

1. A wall tie of the class described, comprising a strip of metal doubled upon itself at intervals along its length so as to provide transversely disposed anchor parts, said anchor parts of equal width with said strip having the ends thereof bent over to form wings extending in the same general direction as the strip and being adapted to be embedded in a wall or the like so as to locate said strip on the face thereof.

2. A wall tie of the class described, comprlsing a strip of metal doubled upon itself at intervals along its length so as'to provide transversely disposed 'anchor parts,

each of said anchorparts having a slit extending inwardly from the-end thereof and having the end bent over to form oppowall or the like so as to locate said strip on the face thereof,

3. A Wall tie of the class described, comprising a strip of metal, transversely disposed anchor parts formed .on said strip, and corrugations formed in said strip crosswise thereof between said anchor parts, said anchor parts being adapted to be embedded in a wall or the like so as to locate said strip on the face thereof, said corrugations being adapted to permit a practical elongation of the portions of the strip between the embedded anchor parts so that such portions may be bowedoutwardly from the face of the wall.

'4. A wall tie of the class described, comprising a strip of metal doubled upon itself at intervals along its length so as to provide transversely disposed anchor parts, and

corrugations formed in said strip crosswise thereof adjacent to the bend in said strip made in the formationof said anchor parts,

said anchor parts being adapted to be embedded in a wall or the like so as to locate said strip on the face thereof, said corrugations being adaptedto permit a practical elongation of portions of the strip between anchor parts so that such portions may be bowed outwardly from the face of the wall. 5. A wall tie of the class described, comprising a strip of metal doubled upon itself at intervals along its length so as to provide transversely disposed anchor parts, each of said anchor parts having a slit extending inwardly from the end thereof and having the end bent over to form' oppositely disposed wings extending in the same general direction as said strip, and corrugations formed in said strip crosswise thereof adjacent to said anchor parts, said anchor parts being adapted to be embedded in a wall or the like so as to locate said strip on. the face thereof, said corrugations being adapted to permit a practical elongation of the portions of the strip between the embedded anchor parts so that such portions may be bowed outwardly from the face of the Wall.
